Simba manejimendi chip IC ndiyo nzvimbo yekugovera magetsi uye chinongedzo chezvese zvigadzirwa zvemagetsi nemidziyo, ine basa rekushandura, kugovera, kuona uye mamwe mabasa ekutonga esimba rinodiwa, chinhu chakakosha kiyi mudziyo wezvigadzirwa zvemagetsi nemidziyo.Panguva imwecheteyo, nekuvandudzwa kweInternet yeZvinhu, simba idzva, hungwaru hwekugadzira, marobhoti uye dzimwe nzvimbo dzekushandisa dziri kubuda, musika wepasi wemagetsi ekutonga machipisi akaunza mikana mitsva yebudiriro.Izvi zvinotevera kuunza kupatsanurwa, kushandisa uye kutonga kwesimba manejimendi IC chip hunyanzvi hunyanzvi.
Power management chip classification
Muchikamu nekuda kwekuwanda kweiyo simba manejimendi ics, magetsi semiconductors akatumidzwa zita rekuti simba rekutonga semiconductors.Izvo chaizvo nekuti akawanda akabatanidzwa maseketi (IC) munzvimbo yekugovera magetsi, vanhu vanowedzera kune simba manejimendi kudaidza nhanho iripo yemagetsi ekupa magetsi.Simba manejimendi semiconductor mune inotungamira chikamu chesimba manejimendi IC, inogona kupfupikiswa seinotevera 8.
1. AC/DC modulation IC.Iyo ine yakaderera voltage control circuit uye yakakwira voltage switching transistor.
2. DC/DC modulation IC.Inosanganisira boost/step-down regulators, uye mapombi ekuchaja.
3. simba factor control PFC pretuned IC.Ipa simba rekuisa dunhu rine simba rekugadzirisa basa.
4. pulse modulation kana pulse amplitude modulation PWM/ PFM control IC.A pulse frequency modulation uye/kana pulse wide modulation controller yekutyaira ekunze switch.
5. linear modulation IC (yakadai semutsara yakaderera voltage regulator LDO, nezvimwewo).Inosanganisira kumberi uye kwakashata regulators, uye yakaderera voltage inodonha LDO modulation machubhu.
6. bhatiri kuchaja uye manejimendi IC.Izvi zvinosanganisira kubhadharisa bhatiri, kudzivirira uye simba rekuratidzira ics, pamwe ne "smart" bhatiri ics yebhatiri data data.
7. Hot swap board control IC (isina kukanganiswa kwekuisa kana kubvisa imwe interface kubva kune inoshanda sisitimu).
8. MOSFET kana IGBT kushandura basa IC.
Pakati peaya masimba manejimendi ics, voltage regulation ICS ndiyo inokurumidza kukura uye inogadzira zvakanyanya.Iwo akasiyana emagetsi manejimendi ics anowanzo kubatanidzwa nehuwandu hwehukama hwekushandisa, saka mamwe marudzi emidziyo anogona kunyorwa kune akasiyana maapplication.
Chechipiri, kushandiswa kwesimba rekutonga chip
Kukura kwesimba rekutonga kwakakura, kusanganisira kwete chete yakazvimirira shanduko yemagetsi (kunyanya DC kuenda kuDC, inova DC/DC), yakazvimirira magetsi kugovera uye kuona, asiwo yakasanganiswa simba shanduko uye simba rekutonga system.Saizvozvo, kupatsanurwa kwesimba rekutonga chip kunosanganisirawo zvinhu izvi, senge linear power chip, voltage reference chip, switching power chip, LCD driver chip, LED driver chip, voltage yekuona chip, bhatiri yekuchaja manejimendi chip zvichingodaro.
Kana dhizaini redunhu remagetsi neruzha uye ripple kudzvinyirira, akakumbira kutora diki PCB nharaunda (semuenzaniso, nharembozha uye zvimwe handheld zvigadzirwa zvemagetsi), simba rekupa redunhu havabvumidzwe kushandisa inductor (seserura) , yenguva pfupi calibration uye inobuda simba renyika inoda kuve yekuzviongorora basa, kudonhedza kudonha kunodiwa voltage stabilizer uye yakaderera simba mashandisiro, mutsara wemutengo wakaderera uye mhinduro iri nyore, Ipapo mutsara magetsi ndiyo sarudzo yakakodzera.Iri magetsi emagetsi anosanganisira anotevera matekinoroji: chaiyo voltage referensi, kuita kwakanyanya, yakaderera ruzha inoshanda amplifier, yakaderera voltage inodonha regulator, yakaderera static ikozvino.
Pamusoro peiyo yekutanga simba rekushandura chip, iyo simba manejimendi chip inosanganisirawo simba rekudzora chip nechinangwa chekushandisa zvine musoro kwesimba.Zvakadai seNiH bhatiri yakangwara inokurumidza kuchaja chip, lithium ion bhatiri yekuchaja uye discharge management chip, lithium ion bhatiri pamusoro pevoltage, pamusoro pezvino, pamusoro pekushisa, chidimbu chekudzivirira chip;Mumutsara wemagetsi ekupa uye backup bhatiri switching manejimendi chip, USB simba manejimendi chip;Kuchaja pombi, akawanda-channel LDO magetsi ekupa, simba sequence control, kuchengetedzwa kwakawanda, bhatiri kuchaja uye discharge management yakaoma simba chip, nezvimwe.
Kunyanya mumagetsi evatengi.Semuenzaniso, inotakurika DVD, nharembozha, digitaalinen kamera uye zvichingodaro, anenge ane 1-2 zvidimbu zvesimba manejimendi chip inogona kupa yakaoma multi-nzira magetsi ekupa, kuitira kuti kuita kwehurongwa kune zvakanakisa.
Yetatu, mamaboard simba manejimendi chip yakanaka kana yakaipa kutonga hunyanzvi
Motherboard power management chip yakakosha zvikuru motherboard, tinoziva kuti chikamu chinoshanda kusangana nemamiriro aya, imwe ivoltage, imwe isimba.Motherboard power management chip ine basa revoltage yechikamu chimwe nechimwe chebhobhobhobho chip.Kana bhodhi rakashata raiswa pamberi pedu, tinogona kutanga taona simba rekutonga chip rebhodhi reamai uye toona kana chip ine inobuda voltage.
1) Chekutanga mushure meiyo mainboard power management chip yaputswa, CPU haishande, kureva kuti, hapazove nekupisa mushure mekunge mainboard yaiswa simba paCPU, panguva ino unogona kushandisa diode tap yemamita. kuti uedze kushorwa kweinductor coil uye pasi kana mita inodonha kukosha kwekupikisa kunokwira kuratidza kuti simba rekutungamirira chip rakanaka, pane zvinopesana, pane dambudziko.
2) Kana iyo peripheral simba rekupa iri yakajairika asi iyo voltage yemagetsi manejimendi chip haina kujairika, unogona kutanga watarisa voltage yeFIELD effect tube G pole, sekuteerera kune akasiyana kukosha kukosha, uye unosimbisa kuti power management chip yakashata.
